Benefits of technology

[0007]Earlier ASGs were intransparent to US and this may entice users of combined US and X-ray imagers to dispense with ASG altogether which in turn caused the X-ray image quality to remain under par. The proposed ASG on the other hand encourages use in combined X-ray and US imaging due to its US transparency thus ensuring high-quality X-ray and ultrasound imaging at the same time.
[0009]According to one embodiment, the distance between lamellae of the grid matches half a wavelength of an ultrasound center frequency. This allows achieving yet better US transparency.
[0028]According to one embodiment, the ultrasound transducer, the anti-scatter assembly and the X-ray detector are arranged in-line. In particular, ultrasound waves pass through the anti-scatter assembly to reach the ultrasound transducer. This allows a compact arrangement and convenient multi-modal imaging operation.
[0036]In one embodiment, the anti-scatter grid device is arrangeable, during operation of the US imaging component, in between an X-ray source of the X-ray component and an ultrasound detector of said US imaging component. This allows easy operation of the imaging system as the anti-scatter device does not have to be removed before one uses the ultrasound imaging component.

Problems solved by technology

However, this type of multi-modal imaging has proved cumbersome in applications.
Also, the image quality in such settings remained behind expectations.

Embodiment Construction

[0045]With reference to FIG. 1, there are shown components of an imaging system IM.

[0046]The imaging system IM is multimodal in the sense that it combines two imaging components that work on different principles: there is an X-ray imaging component XC and there is an ultrasound imaging component USC. Possible, non-exhaustive areas of application include mammography or cardio-vascular imaging.

[0047]Each imaging component can be made to work separately and independent from each other. One component may be used to acquire a first image set and, subsequently thereto, the other component may be used to acquire a second image set. Preferably both components, ultrasound and X-ray, can work concurrently to acquire image sets at the same time of an object to be imaged P. The object is a human or animal (in particular mammal) patient. What is mainly envisaged herein is a human patient or an anatomical part thereof. In the following we will therefore refer to the object as patient P. In one em...

Abstract

An anti-scatter device (ASG) filled with a filler material. The filler material (202) has an acoustic impedance that corresponds to that of human or animal tissue. Furthermore a hybrid X-ray / ultrasound imager (IM) including such an anti-scatter GA device (ASG).

Description

FIELD OF THE INVENTION[0001]The invention relates to an anti-scatter grid, a detector module and an imaging apparatus.BACKGROUND OF THE INVENTION[0002]More and more imaging applications combine X-ray imaging with ultrasound (US) imaging. A mammography system with separate detectors for X-ray and ultrasound is reported in US 2008 / 0242979.[0003]However, this type of multi-modal imaging has proved cumbersome in applications. For instance, some present setups require imaging in two subsequent procedures, one for X-ray the other for ultrasound (US). Also, the image quality in such settings remained behind expectations.SUMMARY OF THE INVENTION[0004]There may therefore be a need for improved multimodal US and X-ray imaging.[0005]The object of the present invention is solved by the subject matter of the independent claims where further embodiments are incorporated in the dependent claims. According to a first aspect of the invention there is provided an anti-scatter assembly for X-ray imagi...
